A method of forming a device includes forming a silicon-containing line continuously extending between a first node and a second node. A first silicide-containing portion and a second silicide-containing portion are formed over the silicon-containing line. The first silicide-containing portion is separated from the second silicide-containing portion by a predetermined distance, and the predetermined distance is substantially equal to or less than a length of the silicon-containing line.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of forming a device, the method comprising: forming a silicon-containing line continuously extending between a first node and a second node; and forming a first silicide-containing portion and a second silicide-containing portion over the silicon-containing line, wherein the first silicide-containing portion is separated from the second silicide-containing portion by a predetermined distance, and the predetermined distance is substantially equal to or less than a length of the silicon-containing line, wherein the forming the first silicide-containing portion and the second silicide-containing portion over the silicon-containing line comprises: forming a silicide-containing layer over the silicon-containing line, such that the silicide-containing layer continuously extends between the first and second nodes; and removing at least a portion of the silicide-containing layer so as to form the first silicide-containing portion and the second silicide-containing portion over the silicon-containing line.
2. The method of claim 1 , wherein the predetermined distance is about 40% or less of the length of the silicon-containing line.
3. The method of claim 1 , wherein the forming the silicide-containing layer comprises: forming a metallic material over the silicon-containing line; and causing the metallic material to react with the silicon-containing line to form the silicide-containing layer.
4. The method of claim 3 , wherein the forming the metallic material comprises performing a physical vapor deposition (PVD) process, a plating process, a plasma enhanced CVD (PECVD) process, an atmospheric pressure CVD (APCVD) process, a low pressure CVD (LPCVD) process, a high density plasma CVD (HDPCVD) process, or an atomic layer CVD (ALCVD) process.
5. The method of claim 1 , wherein the forming the silicon-containing line comprises performing an atomic layer deposition (ALD) process, a chemical vapor deposition (CVD) process, a remote plasma CVD (RPCVD) process, a plasma enhanced CVD (PECVD) process, or a metal organic CVD (MOCVD) process.
6. A method of forming a device, the method comprising: forming a silicon-containing layer over a substrate, the silicon-containing layer including a first portion, a second portion, and a silicon-containing line connecting the first portion and the second portion; and forming a first silicide-containing portion and a second silicide-containing portion over the silicon-containing line, the first silicide-containing portion being separated from the second silicide-containing portion by a predetermined distance, wherein the forming the first silicide-containing portion and the second silicide-containing portion comprises: forming a silicide-containing layer over the silicon-containing line; and removing a portion of the silicide-containing layer, the removed portion of the silicide-containing layer defining a region separating the silicide-containing layer into the first silicide-containing portion and the second silicide-containing portion.
7. The method of claim 6 , wherein the predetermined distance is about 40% or less of a length of the silicon-containing line.
8. The method of claim 6 , wherein the forming the silicide-containing layer comprises: forming a metallic material over the silicon-containing line; and causing the metallic material to react with the silicon-containing line to form the silicide-containing layer.
9. The method of claim 8 , wherein the forming the metallic material comprises performing a physical vapor deposition (PVD) process, a plating process, a plasma enhanced CVD (PECVD) process, an atmospheric pressure CVD (APCVD) process, a low pressure CVD (LPCVD) process, a high density plasma CVD (HDPCVD) process, or an atomic layer CVD (ALCVD) process.
10. The method of claim 6 , wherein the forming the silicon-containing layer comprises performing an atomic layer deposition (ALD) process, a chemical vapor deposition (CVD) process, a remote plasma CVD (RPCVD) process, a plasma enhanced CVD (PECVD) process, or a metal organic CVD (MOCVD) process.
